Honestly he hits the nail on the head on all of these, and I still remember my disappointment on the trashcan Mac Pro when it came out, though amazing how something similar with Apple Silicon, without any expandabillity except for Thunderbolt 4, and now I am excited for it.
How things have changed! Of course the built in Pro Res acceleration will certainly be a boon for editing, but I guess also running on an iMac Pro for the last few years has shown me that I don’t need that much expandability except for more damn Thunderbolt 4/USB C ports (as I already have 2 OWC Thunderbolt 4 hubs, and could use more ports).
